Unfortunately MD can't open vcproj files.

In VS2005, VS switched to a new tools-friendly project/build format
called MSBuild - for everything except C++ projects. People have been
asking them to switch to MSBuild for C/C++ projects too, and that will
happen in VS2010 (with vcxproj files), but the upshot is that MD's
support for MSBuild projects is useless for vcproj projects.

To fully support the new file format, we'd need to
* map the item types from new MSBuild-based vcxproj projects onto MD's
project model
* write an importer for existing c/c++-flavour mdproj (generic MD
MSBuild projects)
* write some xbuild tasks so that vcxproj files could be built with
mono msbuild build engine and the associated xbuild command-line tool
* add support to xbuild for some of the ,NET 4.0 MSBuild features that
vcxproj uses

We could also write an importer/converter for vcproj files, but
considering that VS2010 does that conversion to vcxproj I'm not sure
it's worth the effort.

Unfortunately we don't have anyone actively developing the C/C++ addin
right now, though we do try to ensure that it stays working.

The following explain a bit about vcxproj:

We don't usually create/update the repos for unstable version numbers.
